Antimony equivalent weights

Since we had only 10% sulfur to begin with, we must use some of the sulfur equivalence in the antimony sulfide. One mole of Sb2S3 contains 243.5 grams antimony and 96.192 grams sulfur. (The formula weight of Sb2S3 is 339.692). 39.692/96.192 = 3.53, so each percent sulfur that we need will require 3.53% Sb2S3 to replace it. We need 1.9% sulfur, so we can substitute approximately 6,7% of antimony sulfide. This leaves only 2.3% antimony to go. 

Frankland replied, pointing out that in antimonic anhydride each atom of antimony has five bonds satisfied by oxygen , etc. and that he had also used chlorine compounds. As Japp said A discovery, made by an adherent of the radical theory and correctly formulated by him in terms of the old equivalents, does not become the property of the first adherent of the type theory who happens to translate it into the new atomic weights. Kekule s first reference to valency was in 1854 (see p. 535).
